Site dependent energy loss in Ar scattering from Pt(111)
Using classical trajectory calculations the translational energy ratio of the final and initial energy (Et/Ej) for Ar inelastically scattered from a Pt(111) surface has been investigated for thermal and hyperthermal energies up to 30 eV. The Ar/Pt(111) potential is based on a Hartree-Fock-Slater calculation for an Ar atom with a Pt4-cluster.
